Horn first incapacitated Wan by using the Force to throw a bust of a long-dead Jedi at her, catching the Falleen in the middle of her torso. Again using the Force, Horn threw dozens of datatapes at Minker. As the Brubb deflected the makeshift projectiles, Horn hurled her activated lightsaber at him. Just as Horn vaulted over him, Minker was able to get his own weapon up in time to block the attack. Calling her weapon back to her hand, Horn escaped the archives. Minker gave chase and found that Horn had locked the door through which she had fled, fusing the controls on the other side with her lightsaber to prevent anyone from following her. Minker immediately began to cut through the door with his own weapon, but the doors had been designed to prevent intruders from accessing the Temple, and were not easy to breach, even with a lightsaber. Minker was still cutting through the door when Jedi Master Cilghal arrived, and Minker apologized to the Master for the delay in continuing the chase after Horn. Cilghal, who had sensed that Horn had bolted, ignited her own lightsaber and assisted Minker in cutting through the door. Despite their efforts, Horn managed to escape the Temple, and was captured by Galactic Alliance Security.[1]

Shortly after the incident with Jysella Horn, Minker was assigned to escort the Solo family—consisting of Leia Organa Solo; Han Solo; their daughter, Jaina Solo; and their adopted ward, Amelia Solo—when they attended the Coruscant Livestock Exchange and Exhibition at the Grand Event Center. Jedi Natua Wan also accompanied the group, and while Wan kept an eye on Amelia, Minker brought up the rear. As Minker and Wan were present in an official capacity, they were dressed in their formal brown and white Jedi robes. As they progressed through the exhibition, Minker noticed the journalistJavis Tyrr, who had recorded Horn's actions outside the Jedi Temple and was making a career out of reporting about Jedi behavior. Minker suggested that he have a friendly word with Tyrr, to make him back off from the family outing, but Jaina Solo pointed out that such a move would only encourage the journalist, not deter him. Minker remained vigilant for Tyrr's presence while the group moved into the part of the exhibition that was showcasing dangerous animals such as Nexu and Rancors.[1]

As the group viewed a Nexu and her four cubs, Minker felt a prickle in the Force warning him of danger. He noted that the feeling had been sensed by Leia Organa Solo and Jaina Solo as well, and immediately took hold of his lightsaber. As the three Jedi turned to see if Wan had felt the same sensation, they found her missing. Wan had suddenly succumbed to the same psychosis that the Horn siblings suffered from and was viewing the other members of the group as impostors. Leaving the group, she used her Jedi authority to gain access to the control room of the dangerous animals exhibit. The animals were kept in separate transparisteel pens, with a viewing walkway above the enclosures. Wan activated the exhibits' system for feeding the animals, which opened the pens, while at the same time slowly retracting the walkway into the wall and dropping food from the ceiling. She also plunged the exhibit into darkness and locked the emergency exits. As the gathered crowd began to panic, Organa Solo ordered Minker to begin cutting through the emergency exit closest to their position. Complying, Minker began using his lightsaber to create an exit while Organa Solo used the Force to keep the stampeding crowd back to allow him to work. The Brubb was successful in creating an exit, which in turn stopped the walkways from retracting. Minker's actions allowed the crowd to escape the exhibition hall safely.[1]

With the dangerous animals exhibit cleared, Minker headed for the main exhibition hall where the domesticated pack animals were kept. Wan had opened the animal corrals, causing the animals to stampede and endanger the patrons that had gathered for the exhibition. Minker arrived just as Wan was facing off against Jaina Solo and her mother. The Brubb asked Wan to surrender, citing that she faced three-to-one odds; in response, Wan lunged at Jaina Solo. Both female Solos brought their blades down on Wan's in unison, staggering the Falleen Jedi. At that point, Minker jumped at Wan from behind, slamming his hard head into the back of hers, rendering Wan unconscious. The Solos were surprised with Minker's tactic, but admitted that it had done the job. He then assisted in escorting Wan to the Jedi Temple, where she was interred in the Detention Center.[1]

Minker was a strong and tough individual, able to withstand multiple projectiles hitting him in quick succession. He was also able to headbutt a Falleen in the back of the head with little discomfort to himself. He had a very cheerful and outgoing demeanor, and could generally enjoy himself in most situations. Minker also had some knowledge regarding the training of wild animals, and knew that Nexu cubs could be trained from birth by an experienced handler to become guard animals rather than savage predators.[1]
